* fix(pnpr): pass batch_publish test request bodies by reference The put_json/put_json_with_token test helpers took the JSON body by value but only borrowed it for serde_json::to_vec, tripping clippy's needless_pass_by_value under --all-targets. Take &Value instead, which also drops an unnecessary body.clone() at one call site. * ci: run clippy as a single-OS job and add it to the pre-push hook Clippy was a step inside the three-OS Lint-and-Test matrix, so it ran once per OS even though it lints the same platform-independent source each time. Move it to its own ubuntu-only job, mirroring the existing single-OS doc, format, and dylint jobs (platform-gated cfg blocks are still type-checked per-OS by the test build). It was also missing from pacquet/scripts/pre-push-rust.sh, so a clippy lint that only fires under --all-targets — like the one that just reached main — slipped past local pushes and surfaced only in CI. Add the same --all-targets workspace clippy gate to the hook.

Fast, disk space efficient package manager:
- Fast. Up to 2x faster than the alternatives (see benchmark).
- Efficient. Files inside
node_modulesare linked from a single content-addressable storage. - Great for monorepos.
- Strict. A package can access only dependencies that are specified in its
package.json. - Deterministic. Has a lockfile called
pnpm-lock.yaml. - Works as a Node.js version manager. See pnpm runtime.
- Works everywhere. Supports Windows, Linux, and macOS.
- Battle-tested. Used in production by teams of all sizes since 2016.
- See the full feature comparison with npm and Yarn.
To quote the Rush team:
Microsoft uses pnpm in Rush repos with hundreds of projects and hundreds of PRs per day, and we’ve found it to be very fast and reliable.

Background
pnpm uses a content-addressable filesystem to store all files from all module directories on a disk. When using npm, if you have 100 projects using lodash, you will have 100 copies of lodash on disk. With pnpm, lodash will be stored in a content-addressable storage, so:
- If you depend on different versions of lodash, only the files that differ are added to the store.
If lodash has 100 files, and a new version has a change only in one of those files,
pnpm updatewill only add 1 new file to the storage. - All the files are saved in a single place on the disk. When packages are installed, their files are linked from that single place consuming no additional disk space. Linking is performed using either hard-links or reflinks (copy-on-write).
As a result, you save gigabytes of space on your disk and you have a lot faster installations!

why it works fine with the Node.js ecosystem, read this small article: Flat node_modules is not the only way.
